FLUID-DISPENSER.

Application filed July 20, 1914. Serial No. 851,967.

To all whom t may concern Be it known that I, CHARLES A. HiscH- MAN, a citizen of ythe United States, residing at Springlield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Fluid-Dispensers, of which the following is a specilication.

My invention relates to fluid dispensing apparatus and particularly to means for agitating the fluid at the time of its withdrawal.

The object of the invention is to simplify the structure as well as the means and mode of operation of such devices whereby they will not only be cheapened in construction, but will be more efficient in use, positive in action, easily operated, and unlikely to get out of repair.

With the above primary and other incidental objects in view, as will more fully appear inthe specification, the invention c0n` sists of the features of construction, the parts and combinations thereof, and the mode of operation, or their equivalents, as-

hereinafter described and Set forth in the claims.

Referring to the drawings, Figure 1 is a longitudinal sectional View of the assembled device in its normal or closed position. Fig.

containers of milk or butter-milk or similar commodities in which the more desirable portions tend to rise to the top, ory in dispensing paints and other commodities which contain heavier portions tending to settle I toward the bottom.

the bottom thereof is a cylinder 2, the opposite heads of which are perforated as at 3 and 3a.' Extending from the cylinder 2 through the wall of the vat or container is a tubular conduit 4. Any suitable means such as the packing gland 5 and the jam nut G with the washer 7 of packing material may be employed to prevent the leakage of the contents of the receptacle around the conduit. Located upon the portion of the conduit projecting beyond the vat or container is a pendant discharge nozzle 8 communicating with the interior of the conduit 4. lVithin the cylinder 2 is a reciprocatory piston 9, the stem 10 of which extends through the tubular conduit 4 and terminates in a handle 11. A closure cap is provided upon the extremity of the conduit 4 which provides a bearing for the outer portion of the stem 10 which reciprocates therethrough. r1`he interior diameter of the tubular conduit 4 is somewhat greater than the diameter of the stem 10. Substantially midlengthv upon the stem 10 is a pistonlike closure body l2, moving therewith, which as'- sumes a position forward of the discharge nozzle 8, as shown in Fig. 2.

In the normal position of the parts, as shown in Fig.1, the contents of the container are prevented from escaping through the conduit 4 and the discharge nozzle 8 by the closure body 12. When it is desired to discharge a portion of the contents of the container, the piston 9 is drawn forward by means of the handle 11. This causes the contents of the cylinder 2 to be forcibly discharged through the yorifices 3a in the forward head of the cylinder, while at the same time, additional fluid is drawn into the cylinder in the rear of the piston through the orifices 3. The discharge and injection of the fluid from and into the cylinder by the movement of the piston violently agitates the contents of the vessel or container thoroughly mixing any separated portions of unequal density. As thepiston 9 and stem 10 continue tol move forward, the closure body 12 is drawn to a position beyond the discharge nozzle 8, as shown in Fig. 2. In this position the parts come to rest. The conduit-4 is then open for a discharge of the fluid. The discharged fluid enters the cylinder 2 from the vessel through the orifices 3a and passes thence through the conduit 4 about the 'stem 10, escaping through the nozzleI 8. To increase the capacity ofthe apparatus, that portion of the stem intermediatethe closure body 1-2 and the piston head 9 is preferably of reduced diameter. Uponv the closing operation, the flow 5 of the contents from the container is arrested upon the initial movement of the piston by the movement of the closure'body 12 past the discharge nozzle 8. After the flow of the contents has been arrested, the piston 1o continues to move rearward expelling the contents of the cylinder through the orifices 3 and drawing a new charge thereinto through the orifices 3a. This again violently agitates the contents of the vessel preparatory to theneXt Withdrawal. It is to be noted that the agitation of the fiuid is automatically caused by the opening of'the faucet. vSuch agitation, however, isproduced before the faucet is opened sufiiciently to permit the flow of the contents. Upon the return movement, the agitation occurs after the faucet has been closed.

In Fig. 3 there is shown a modification of A the' construction previously described in which the' agitator and faucet are independ- A ent and separate one from the other. In this construction, the cylinder 2 is provided with a tubular conduit 13, the bore of which is substantially 4equal to the diameter of the stem 10 ofthe piston 9.A The stem 10 of the piston projects through the tubular conduit 13, as before described, and carries at its extremity the handle 11. The conduit 13 is provided with a pacln'ng gland 5 and jam nut 6, as before described. In this connozzle 8 leading from the conduit and no closure member 12. Adjacent to the agitator is a faucet 14 of any suitable construc- 40 tion'. In using this form of device the handle 11 is withdrawn and returned to reciprocate the piston 9 within the cylinder 2 thereby causing they contents ofthe cylinder to' be forcibly discharged through the orifices 3 and 3 and new charges drawn thereinto. This' violently agitates the contents of the vessel immediately after which the faucet. 14 is opened to withdraw the contents in the `usual manner. The particular arrangement as shown in the drawings, wherein the cylinder 2 is located in a horizontal position adjacent to the bottom of the vessel or c o'iitainer, has been found especially efficient in agitating such commodities as milk or but- .ter-milk and is far superior to any method of a-gitating such commodities by stirring or by ana'gitatorworking from the top or in a vertical position. l

From the above description it will b e apparent that there is thus'provided a device of the character described, possessing the particular featuresl of advantage before enususceptible of modification in its form, proportion, detail construction or arrangement struction, however, there is no discharge merated as desirable but which obviously isof parts, without departing from the principle involved or sacrificing any of its advantages.

Having thus described my invention, IV

claim:

1. In-a Huid dispensing apparatus, a vessel having a discharge orifice, a movable rocatory actuating rod common to both the` piston and the movable closure for the discharge orifice, said rod being adapted by its initial reciprocatory movement to actuate the piston to agitate the contents of the vessel and by further reciprocatory movement to move the closure member to permit the discharge 'ofthe agitated contents of the vessel.

2.
